The California Gold Rush (1848–1855) began on January 24, 1848, when gold was found by James W. Marshall at Sutter's Mill in Coloma, California. The first to hear confirmed information about gold in California were residents of Oregon, the Sandwich Islands (Hawaii), western Mexico, and Central America. They were the first to go there in late 1848. All told, the news of gold brought some 300,000 people to California from the rest of the United States and abroad. Of the 300,000, approximately half arrived by sea and half came overland from the east, on the California Trail and the Gila River trail.

The effects of the Gold Rush were substantial. San Francisco grew from a small settlement of about 200 residents in 1846 to a boomtown of about 36,000 by 1852. Roads and other towns were built throughout California. In 1849 a state constitution was written, and a governor and legislature were chosen. California became a state as part of the Compromise of 1850.
